Crinum asiaticum

Today’s photograph, the third entry in the “Tropical Biodiversity” series, was taken in the Life Sciences Building Greenhouses of the Univ. of Connecticut by sftrajan@Flickr (a different Eric from San Francisco than the well-known contributor and commenter). Much appreciated! The original image was submitted via the Botany Photo of the Day Flickr Pool.

Crinum asiaticum was featured on Plant of the Week (main page more than a decade ago, but it’s the first time a Crinum has appeared on BPotD. Crinum contains about 100 species. Plants of the genus typically grow at low elevations in wet areas (e.g., shores, swamps).

Commonly known in English as poison bulb, Crinum asiaticum is widely cultivated in tropical and subtropical areas (it is native to tropical Asia, Mauritius, northern Australia and some Pacific Islands). Yet again, the Plants of Hawaii web site provides an extensive collection of additional images: Crinum asiaticum.

As an aside to local readers, the UBC Botanical Garden Indoor Plant Sale continues until 5pm on Friday (still a good selection of plants remaining!).

    I’m not sure which of the crinums is used as a relatively common aquarium plant, but mine grows beautiful strap like leaves up to 3 ft long (In an aquarium the leaves end up as a beautiful interwoven mass at the top, providing haven and shade for the fish. Another one I use in aquaria, C calimastratum, has long thin leaves with tightly crinkled edges, and the largest ones on mine are about 18 inches in length. For aquarium culture, Crinums are planted with only the very bottom of the bulb under the gravel, and grow totally submersed Is C. asiatica ever grown as an aquarium plant? By the way, even though I almost never comment, I want to say that your site is the first thing I look at every day. You do such a fantastic service for us plant lovers. Maybe a series on aquarium plants would be nice (As you can guess, I’m an aquarist and I admit I am very biased here, LOL).

    Why is it called poison? What does it do? It’s very pretty.
